MECHANICAL BUTTON.

Specification of Letters Patent.

Patented Feb. 1 1, 190s.

Applioationled January 23. 1906. Serial No. 297.417.

To all whom it may concern:

Be it known that I, FRANCIS STAsHKo, a subject of the Emperor of Austria-Hungary, residing at No. 509 East Fifth street, New York city, State of New York, have invented certain new and useful Improvements in Mechanical Buttons, of whichthe following is a clear, full, and exact description.

The obj ect of this invention is to provide an improved mechanically secured button which will be cheap to make, easy to attach to cloth, serviceable in usage and sightly in appearance.

The scope of my invention will be pointed out in the claims.

In the accompanying drawings, Figure 1 is a central vertical section on the line -r of Fig. 2 of my preferred form of button; Fig. 2 is a plan of the same; Fig. 3 is a detail of the shank and its retaining disk; Fig. 4 is a plan of Fig. 8 Fig. 5 is a plan of. the tubular standard which is to be attached to the button and which carries the retaining spring; Fig. 6 is a transverse vertical section of the standard; Fig. 7 is a detail view of the retaining spring; Fig. 8 is a vertical transverse section of a modified form of button; Fig. 9 is a detail of the spring shown in the modification of Fig. 8; Fig. 10 is a vertical central section of still another modification; Fig. 11 is an underneath plan of the standard of Fig. 10; Fig. 12 is a still further modification shown in vertical section; Fig. 13 is a plan of the interior tube shown in Fig. 12..

In my preferred form of button shown in Figs. 1 to 7, the shank 2 is formedwith at least one tooth but preferably with a number of teeth 4() along one side of the same, while the top of the shank is formed tapered that it may readily penetrate cloth. To the lower end of the shank I preferably rivet a retaining disk 1. The button surface of body '7 may be formed of any suitable material, bone or the like, and in my preferred modification I have shown it attached to a central tubular standard 5 set into a recess in the button head 7 and secured by cement 8 around its lower edge. The tubular standard is formed with a central bore 5, and with an opening 9 near its lower edge opening from a groove 9 on the exterior of the shank. A spring 10 having one end inwardly bent occupies a position upon the shank with its inwardly bent end penetrating the opening 9 and its annular portion engaging t e groove 9 after a tubular concentric portion 4 has been slid over the shank 5. Said tubular portion 4 being adapted to rest against a spring 6 at its upper end, which -spring is contained in an annular recess 4 in the standard 5. It will thus be seen that the spring 6 will hold the tubular portion 4 against the spring 10 and present the appearance of a one-part button and shank. I prefer to form integrally with the tubular portion 4, an annular depending rim 30. In use the shank of this button is forced through the cloth, as shown in Fig. 1, and the shank is then inclosed by the tubular standard 5 which is slipped down upon it until the rim 30 is tightly pressed into the goods immediately above the outer periphery of the disk 1, when the spring 10 will be caused by its inwardly turned end to grasp at least one of the teeth in the shank, and the whole firmly held in position. The shank may fit the bore of the standard tightly, if desired. If the user wishes to detach this button he may, by exerting an unusual force upon the button head, turn the same to cause the inwardly turnedend of the spring 10 to ride up upon the smooth part of the shank 2 to allow of its release, whereupon an outward pull u on the button will detach the same from t 1e shank. 4

In the modification shown in Figs. 8 and 9, the button 7 is secured to a tubular standard 41, and the tubular portion 40 provided with annular depending disk 30 is caused to fit against a 'shoulder portion on the part 41 while the lower edge of the standard 41 has riveted to it a plate 42 after such assembly. Between the lower face of the tubular portion 40 and the disk 42, I insert the spring 12 shown in Fig. 9, so that its inner end 43 may penetrate an opening in the lower part of the standard 41 in similar manner to that described in reference to Figs. 5 and 6. In operation this device is used in the same manner as that before described.

In the modification shown in Figs. 1'0 and 11, a sheet metal portion 14 is shown expanded into a recess in the lower portion of the button head 16. In this modification it is this sheet metal portion 14 which carries the tubular depending edge 30. The tubular standard 15 inthis case is formed of sheet metal expanded into the upper closed end of the tubular portion 14. This standard 15 is also formed with a central opening or bore adapted to receive the shank portion 2 and has an inwardly projecting finger 13 struck out from its lower end and adapted to be engaged by the shank 2, as before described.

I claim as lrny invention: 1. A mechanically secured button cornprising a shank having at least one tooth, a

circular retaining disk secured to its lower end in combination with a button top having a depending tubular standard with a central opening, a concentric portion surrounding said standard and provided with a depending disk of'substantially the diameter of the retaining disk on the shank, a spring at the lower edge of the standard adapted to engage the notched shank and to hold the portion carrying the circular disk in place.

2. A mechanically secured button comprising a shank having at least one tooth, a circular retaining disk secured to its lower end in combination with a button top having a depending tubular standard with a central opening, a concentric portion surrounding said standard and provided with a depending disk of substantially the diameter of the retaining disk on the shank, a spring at the lower edge of the standard adapted to engage the notched shank and to hold the portion carrying the circular disk in place, a recess in the upper portion of the standard, a spring in said recess against which the upper end of the concentric portion may rest.

Signed at New York city county of New York this 6th day of January, 1906.
